BURNHAM C. STICKNEY, OF ELIZABETH, 4NEW JERSEY, ASSIGNOR TO UNIONTYPEWRITER COMPANY, OF JERSEY CITY, NEW JERSEY, A CORPORATION OF .NEWJERSEY.

TYPE-WRITING MACHINE.

Specification of Letters Patent.

.\ T all whom it may concern:

Be it known that I, BURNHAM C. STICK- NEY, citizen of the United States,and resident of Elizabeth, in the county of Union and State of NewJersey, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

This invention relates to typewriting machines, particularly-those knownas visible writers, and its objects are to provide means for regulatingthe strength of the blows of the types, and to improve and simplify thecase-shifting mechanism.

My invention consists in certain combinations of devices, features ofconstruction and arrangements of parts, all as will be hereinafterdescribed and particularly pointed out in the concluding claims.

In the drawings forming part of this speciiication, Figure 1 is acentral longitudinal vertical section o f'a front-strike typewritingmachine embodying my present improvements in one form. Fig. 2 is asectional plan showing the type-bar segment frame and its connections,including means lfor effecting line horizontal adjustments thereof.

In the views, like parts are identified by like signs.

The framework of the machine comprises a rectangular base l, cornerposts 2, and top.

plate 3. Above the top plate is supported in the usual manner a platen4, which as usual is mounted upon a carriage 5, the movements whereofare controlled by the usual feeding mechanism (not shown). Radial typebars 6, carrying at their forward ends upper-case types 7 and lower-casetypes 8, are pivoted at their rear ends upon a curved fulcrum rod 9, thelatter being mounted in a vertically disposed segment 10, which isslotted radially at 11 to receive the type bar hubs. The type bars mayswing about said fulcrum rod 'upwardly and rearwardly against the platen4.

The movements of the type bars are effected by means of a series of pulllinks 12, pivoted to the'type bars at 13 and extending rearwardlytherefrom, and pivoted at their rear ends to upstanding sub-levers 14.The latter are pivoted between their ends at 15 to horizontal key levers16, and below the key levers are'forked at 17 to embrace a transi versefulcrum rod 18, whereby when the key levers are depressed, said.sub-levers are caused to vibrate rearwardly to pull the type bars up toprint.' `Said key levers 16 are fulcrumed at their reas upon atransverse rod 19, and at their forwardnds bear keys 20. By means of'springs 21 said key levers are pressed up against a pad 22, provided\upon the under side of a transverse bar 23 forming part of theframework of the machine. l

The segment 10 ismovable up and down to enable the different `types 7and 8 to print, the movements of the segment being limited by means ofsuitable stops 24 and 25. The segment 10 forms a portion of a frame,which also comprises downwardly extendin integral side arms 26. Thelatter are hingen at their lower ends at 27 to a pair of arms 28,

`which extend forwardly from the segment frame and are fixed upon ahorizontal transverse rock shaft 29, whereby said arms 28 are enabled toguide the lower portion of the segment frame in its up and downmovements. As a cooperating guide, I provideia link 30, whose rear endis pivoted at 31 to a lug 31a depending from the segment about midway ofthe width of the latter, and extends forwardly therefrom and is pivotedat its forward end at 32 to -an adjustable part upon the bar 23 of theframework. It will be seen that the guide arms or links 28, 28 and 30constitute a complete supporting and uiding means for the segment frame,said inks and frame taken together 'forming a link motion, and themovements of the segment with its type bars -being vertical or otherwiseto conform to the. positions of the types upon the type bars. Theshifting movement of the segment is effected by Patentaiuay, 190s.l l

means of a shift key 33, provided upon a lever 34, which is pivoted at35 upon an arm 36 extending forwardly from the rock shaft 29 and rigidtherewith; said lever extending rearwardly from said pivot and beingforked at its rear end at 37 to enga e a fixed fulcrum pin 38 projectingfrom t ie side wall. of the machine base. It will be seen that bydepressing the shift key 33, the lever 34 is vibrated, carrying down thearm. 36, and raisin@r the arms 28, together with thesegment lframe andtype bars, to enable the uper case types to print. Upon relief of thekey from pressure, the segment gravitates to normal position.

The ty e bars are illustrated as provided about midway between theirends with nibs 39, which, when the types are close to or touching theplaten, contact with a stop or anvil 40, of-plreferably segmental form,the

urpose of t e anvil being to insure even blows of the types, or tosecure perfect type impressions. The type bars may be somewhat'springy,and may vcontact with the anvil before the types quite touch theplaten,'

the remainder of the movements of the types being permitted by thespring of the typebars. In this wayT the anvil prevents the type blowsfrom being too heavy and marring the appearance of the work. The anvilspans the segment above the type bars and type bar links, the anvilbeing above the segment and adjustablysecured to the segment at the endsof the latter by means of screws 41 and slots 41a.

It will be understood that the type is very close to the platen when thenib on the type bar contacts with the anvil, and hence that when severalsheets of paper are passed around the laten, as in manifolding, thetypes strike t ie aper freely without contact with the anvil, t erebylosing the advantage of the latter. In order to avoid the loss ofaccuracy arising from this and other causes, I make the anvil adjustablein'the direction of type blows, this adjustment bein@ referably effectedby means of a device which adjusts not only the anvil itself but alsothe segment whereon the anvil is fixed. To this end I provide foradjusting the su port 42, to which the forward end of the guic e link 30is secured. Said sup ort is mounted for forward and backwar movementupon the cross bar 23, and is rovided at its rear end with a lug 43,into w ich is threaded a screw 44, whose forward end is provided withcollars 45, one upon each side of a lug 46 formed -upon the cross bar23. Said collars prevent endwise movement of the screw, so that byturning the latter, the support 42 is advanced or retracted, and thelink 30 is moved endwise accordingly, thereby tipping the type barsegment, together with the anvil thereon, about the hinge 27. Thus theanvil may be readily adjusted to accommodate different thicknesses ofpaper, or different sizes of platens, or to compensate for other slightvariations. The support 42 is fastened in its adjusted position by meansof a set screw 47, tapped into the cross bar, and 'bearing u on thesupport, which works in a horizonta perforation or bearing 48 formed jin said cross bar.

Variations may be resorted to within the scope of my invention, andportions of my improvements may be used without others. l

If desired, the anvil may be adjusted so that the type strikes the pa erpractically simultaneously with the striking of the type bar against theanvil.

What I claim as new and desire to secure by Letters Patent, is
